Amazon Route 53 Auto Naming simplifies the management of DNS names and health checks for microservices that run on top of AWS when microservices scale up and down. You can call the Auto Naming APIs to create a service, and then register instances of that service with a single API call. Amazon Route 53 Auto Naming will automatically populate the DNS records and optionally create a health check for the service endpoint. When a new service instance is registered, you can access it by making a simple DNS query for the service name.

You can use Amazon Route 53 Auto Naming APIs in the following AWS regions: US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon), EU (Ireland), EU (Frankfurt), EU (London), Asia Pacific (Tokyo), Asia Pacific (Singapore), and Asia Pacific (Sydney) regions.
